Interest in trying to implement P2643R2 atomic features

["Teodor Spæren" <teodor@sparen.no>]

Hey!

My name is Teodor and I would be interested in trying to implement the 
new features described in 
https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2024/p2643r2.html

I've not contributed to libstdc++ or gcc before, but I think this might 
be a good first area, as it's mostly reusing the already implemented 
internals. The work I would want to do, would involve implementing the 
new additions and write simple tests to check for behavior.

I was told to email here to ask about if this is something that sounds 
reasonable and how I would get started on this process.

The second question I have, is that I would be interested in trying to 
maybe implement this in LLVM also. As far as I understand this would not 
be an issue, but I want to ask about it, if there are potential 
licensing issues.

I don't have a timeline on the completion of the work, but I don't 
expect it to happen overnight as there will be many new things to learn 
as I try to modify the std for the first time.

I hope I can be of help,
